FIELD OF THE INVENTION

The present invention relates to methods for treating tumors in subjects by using recombinant interferon, and to methods for treating solid tumors, including lung cancers in subjects. The present invention further relates to non-surgical methods for eliminating tumors or reducing the sizes of tumors in subjects, or preventing postoperative tumor recurrence and/or metastases and/or prolonging tumor free survival in subjects by using a recombinant interferon (rSIFN-co) with changed spatial configuration, either alone, or in conjunction with radiotherapy, chemotherapy, and/or anti-tumor drugs such as biological agents, targeted drugs and the like.

BACKGROUND OF THE INVENTION

Cancer is one of the major causes of death in people around the world. The total number of cases worldwide continues to increase. According to the statistics of the world health organization (WHO), it is estimated that the global cancer deaths will be increased by 45% (from U.S. Pat. No. 7,900,000 to Ser. No. 11/500,000) from 2007 to 2030, and the new cases of cancer will zoom from Ser. No. 11/300,000 in 2007 to Ser. No. 15/500,000 in 2030 in the same period, wherein the incidence rate and the death rate of the lung cancer ranks first in the global malignant tumors. According to the statistical data, the amount of the worldwide new cases of lung cancer every year is more than 3,000,000 and increases continuously (see Gray, J. et al. Chest, 2007, 132, 56S-68S). The number of deaths caused by lung cancer is more than 1,300,000 around the world every year, which is more than the sum of the number of cancer-related deaths caused by other three common cancers (breast cancer, prostate cancer and colorectal cancer).

The classic methods for treating cancer include surgical therapy, radiotherapy and chemotherapy. However, the surgical therapy is not suitable for all types of solid tumors. The surgical therapy may not eliminate cancer cells thoroughly due to metastatic lesions and the like, so as not to achieve the purpose of cure. Radiotherapy is only suitable for the tumors situated at positions that are sensitive to rays, take muscles as tumor beds and have better blood circulation, and the radiotherapy may accidentally injure normal cells to cause various side effects, so as to affect the quality of life of the patients. The effect of the chemotherapy as the systemic treatment means is determined by the types and the states of cancers. Chemotherapy can suppress the growth and the spread of the cancers more especially, and same with the radiotherapy, the chemotherapy can also accidentally injure normal cells to affect the quality of life of the patients.

Surgical therapy can be performed to eliminate tumors, improve the quality of life and provide time for follow-up treatment for some early or medium-term solid tumor patients; but for some advanced patients with metastasized solid tumors, the treatment methods in the prior art are only chemotherapy, radiotherapy or combining the chemotherapy, radiotherapy and other treatment methods when the quality of life is obviously affected and life is even threatened, these treatment methods are not ideal in effects and cannot achieve the purpose of eliminating the tumors and completely alleviating the condition of the patients.

According to the mass data, the existing methods for treating cancer, in particular, chemotherapy, cannot obtain the satisfied treatment effect for advanced lung cancer patients, and the number of complete remission (CR) cases is few and is even zero. For example, in the clinical trial of 78 cases which employed cis-platinum for combining Navelbine, Gemzar and Taxotere, respectively, to treat advanced non-small cell lung cancers, no complete remission appeared in any case (see Song, Y. et al, Journal of Modern Oncology, 2005, 13(4), 494-496); however, in the clinical observation of 1155 cases which employed four chemotherapy protocols (Cisplatin+Paclitaxel, Cisplatin+Gemcitabine, Cisplatin+Docetaxel, and Carboplatin+Paclitaxel) for treating the advanced non-small cell lung cancers, complete response was observed, but the complete response (CR) rate was less than 1% (see Schiller, J. H. et al. N Engl J Med, 2002, 346(2), 92-98); and in a random, double-blind, control and multicenter III-stage clinical research which employed recombinant human endostatin for combining NP to treat the advanced non-small cell lung cancers, the 486 evaluable cases in the test group and the control group yielded no cases of complete remission (see Wang, J. W. et al, Chinese Journal of Lung Cancer, 2005, 8(4), 283-290).

In the recent 20 years, due to the in depth research on the cell biology, molecular biology, tumor immunology and the like and the development of the bio-engineering technology, the biotherapy has become the important treatment means for cancer treatment after surgical therapy, radiotherapy and chemotherapy has been performed.

Since Isaacs and Lindenmann discovered interferon (IFN), interferon has been widely researched. Interferon (IFN) is a kind of soluble protein produced by a variety of cells which has many important biological functions, including anti-viral, anti-tumor, and immunoregulatory functions. Interferons can be divided into type I, type II, and type III interferons according to the differences in the types of producing cells, receptors and biological activities, etc. Type I IFNs, which are mostly induced by viruses and synthetic double-stranded RNA, are also known as anti-viral interferons. There are three forms of type I interferons: interferon-alpha or alpha-interferon (IFNα), interferon-beta (INFβ) and interferon omega (IFNω).

In recent years, many companies in the world have engaged in the research of interferon. For example, U.S. Pat. Nos. 4,695,623 and 4,897,471 disclosed new types of human interferon polypeptides which possessed amino acid sequences containing the common or predominant amino acids found in naturally occurring α-interferon polypeptides. One new type of interferon was named IFN-con (consensus interferon α). Compared with leukocyte interferon or other type I interferons, studies have shown that recombinant IFN-con has higher anti-viral, anti-proliferative and natural killer cell activities in vitro. By the end of 1997, the FDA had approved the use of human IFN-con, which was produced by US Amgen and sold under the brand name INFERGEN® (interferon alfacon-1), for clinical treatment of hepatitis C.

It is generally known that the amino acid sequence of a protein can determine the three-dimensional structure of the protein and further determine the functionality thereof. However, in recent years, evidence shows that synonymous mutation(s) of the nucleotide sequence encoding the protein (that is, codon mutation(s) with no change in the amino acid sequence of the encoded protein) can affect the spatial structure and the function of the encoded protein, namely, the nucleotide sequence with synonymous mutation(s) can express and generate proteins with different final spatial structure and different function compared with the wild type protein (see Sarfaty, C. K. et al. Science, 2007, 315:525-528).

A recombinant interferon (rSIFN-co) which has enhanced therapeutic effects, smaller side effects and can be used in a larger doses was disclosed in U.S. Pat. No. 7,364,724, U.S. Pat. No. 7,585,647, U.S. Pat. No. 8,114,395, CN 1740197 A, CN 101001644 A, US 2009/0123417, US 2011/0158941 and WO 2011072487A1. This recombinant interferon, rSIFN-co, has the same amino acid sequence as that of INFERGEN®, but the encoding nucleotide sequences of this recombinant interferon, rSIFN-co, and that of INFERGEN® are different (i.e. synonymous mutations exists in the nucleotide sequence encoding the recombinant interferon, rSIFN-co), resulting in changes in spatial configuration of the recombinant interferon, rSIFN-co, and qualitative changes in its biological efficacy.

DETAILED DESCRIPTION OF THE INVENTION

The inventor found that rSIFN-co can be advantageously used to control cancer, either alone or in combination with other anti-cancer therapies, as a first line or second line monotherapy or in combination with other treatment modalities. The advantages are: Firstly, the recombinant interferon (rSIFN-co) has broad-spectrum anti-tumor effects, which is effective to treat both solid tumors and non-solid tumors. At the same time, rSIFN-co has good synergetic effect with existing treatment means such as surgical therapy, chemotherapy, radiotherapy, other biotherapies and other anti-tumor drugs. Secondly, rSIFN-co has low toxicity, which means that little or no harm to normal cells has been observed when rSIFN-co is used in large doses. Thirdly, rSIFN-co is convenient to use and can be directly applied to tumors located in any part of the body. Thus, rSIFN-co can be used by subcutaneous or intramuscular injection to control systemic progression of tumor, by intrapleural or abdominal perfusion to eliminate effusion and intrapleural or abdominal tumors, by topical or local injection to eliminate primary or metastatic tumors, and by infiltration (transdermal) administration to treat tumor lesions in bone, skin, muscle, prostate and the like. Also, rSIFN-co can be administered by aerosol inhalation or by nasal spray.

According to the above advantages of rSIFN-co, its effective rate on tumors, as a monotherapy and as one element of a combination therapy, is not lower than 90%. With regard to early or medium-term cancer cases, rSIFN-co can be used after surgery in place of chemotherapy and effectively prevent recurrence and tumor metastasis or prolong the period of disease-free survival; with regard to advanced cancer cases or cancer cases that are not indicated for surgery, rSIFN-co can be used to eliminate or reduce the size of tumors without surgery; with regard to tumors that are not indicated for surgery, rSIFN-co can be used to transform the tumors into ones for which surgery is possible, that is, turning a non-resectable tumor into a resectable tumor, thereby creating conditions appropriate for surgery. Therefore, rSIFN-co, alone or in combination with other one or more anti-tumor therapy, is capable of controlling cancer in a large number of instances.

Compared with the IFN-α2b as published and the interferon such as interferon alfacon-1 (INFERGEN®), which has the amino acid sequence of SEQ ID NO: 1, but is not encoded by the nucleotide sequence of SEQ ID NO: 2, the three-dimensional structure of the present recombinant interferon (rSIFN-co) is different from the three-dimensional structure of IFN-α2b (see FIG. 1, wherein in the side view and the top view in the FIG. 1, the red represents rSIFN-co, the green represents IFN-α2b, the red is black in the black-and-white print drawing, and the green is grey in the black-and-white print drawing) and the computation model structure of the interferon alfacon-1 (see KORN, A P, Journal of Interferon Research 1994, 14:1-9). According to the comparison result between the present recombinant interferon and the interferon alfacon-1, there are obvious differences between the AB loops of the two, and their BC loops also cannot overlap completely (see FIG. 2).

In addition, after intramuscular injection of the present recombinant interferon into subjects whose BMI ranged from about 18 to about 23, the time of blood sample collection was plotted against the concentration of 2-5 A oligonucleotidase (also referred to as 2′,5′-OAS) in the serum of the subjects. The chart generally shows a two-peak pattern, and the resulting area under the curve of this chart is significantly greater than that of interferon alfacon-1 (INFERGEN®) after injection under the same conditions. Furthermore, the half-life period of this recombinant interferon is longer than that of interferon alfacon-1 (INFERGEN®) after injection into the body (see CN 1740197A; Zeng, J. P. et al. Modern Preventive Medicine, 2008, 35(5), 982-984).

The experimental results have also confirmed that the present recombinant interferon is more effective than any interferon used clinically at present (including interferon alfacon-1 (INFERGEN®)). For example, for HBV, the present recombinant interferon is capable of not only inhibiting DNA replication of HBV, but also inhibiting secretion of both hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg). The efficiency of inhibiting DNA replication of hepatitis B core antigen (HBcAg) by this interferon is about twice that of interferon alfacon-1 (INFERGEN®). The in vitro pharmacodynamics of the present recombinant interferon shows that it is capable of not only inhibiting the DNA replication of HBV, but also inhibiting secretion of both hepatitis B surface antigen and hepatitis B e antigen. The cytotoxicity of the present recombinant interferon is only ⅛ that of the current clinically used interferons, but its antiviral activity is as much as 5-20 times greater; meanwhile, the biological responses of the present recombinant interferon is more effective, more broad-spectrum and longer lasting in the human body (see CN 1740197A).

Furthermore, with respect to prevention of viral diseases or treatment of tumor, the present recombinant interferon shows higher antiviral activity and less side effects compared with any other interferons (including interferon alfacon-1 (INFERGEN®)). For example, this recombinant interferon possesses not only an antiviral activity 20 times as great as that of the interferons currently in clinical use, but also a more effective inhibiting tumor cell growth or promoting apoptosis function compared with recombinant human interferon α.

Thus, the present recombinant interferon has a different spatial configuration, enhanced biologic activities and/or different pharmacokinetics characteristics as compared with the interferon such as interferon alfacon-1 (INFERGEN®), which has the amino acid sequence of SEQ ID NO: 1, but is not encoded by the nucleotide sequence of SEQ ID NO: 2.

Therefore, in some embodiments, the present recombinant interferon has the amino acid sequence of SEQ ID NO: 1, such as consisting of the amino acid sequence of SEQ ID NO: 1. In some embodiments, the present recombinant interferon is encoded by the nucleotide sequence of SEQ ID NO: 2. In some embodiments, the present recombinant interferon has the amino acid sequence of SEQ ID NO: 1, and is encoded by the nucleotide sequence of SEQ ID NO: 2. Further, the recombinant interferon comprises the amino acid sequence of SEQ ID NO: 1, and is encoded by the nucleotide sequence of SEQ ID NO: 2. Still further, the recombinant interferon is consisted of the amino acid sequence of SEQ ID NO: 1, and is encoded by the nucleotide sequence of SEQ ID NO: 2.

In some embodiments, in comparison with interferon such as interferon alfacon-1 (INFERGEN®), which has the amino acid sequence of SEQ ID NO: 1, but is not encoded by the nucleotide sequence of SEQ ID NO: 2, the present recombinant interferon has a changed spatial configuration and/or enhanced biologic activities and/or different pharmacokinetics characteristics. For example, the present recombinant interferon has a changed spatial configuration and enhanced biologic activities, changed spatial configuration and different pharmacokinetics characteristics, or changed spatial configuration, enhanced biologic activities and different pharmacokinetics characteristics. The enhanced biological activities include: enhanced antiviral activity, enhanced tumor cell growth inhibition or proapoptotic effect, less side effects and/or could be used in large dose (e.g. each dose >10 million IU). For example, the enhanced biological activities can be enhanced antiviral activity and/or enhanced tumor cell (such as breast cancer cell or cervical cancer cell) growth inhibition or proapoptotic effect (see Zheng, J. et al. J Sichuan Univ (Med Sci Edi), 2010, 41(1), 29-34; Chen, Y, et al. J Sichuan Univ (Med Sci Edi), 2008, 39(5), 715-718). The different pharmacokinetics characteristics include: after intramuscular injection of the recombinant interferon in subjects whose BMI ranged from about 18 to about 23, the time of blood sample collection was plotted against the concentration of 2-5 A oligonucleotidase in the serum of the subjects, and the resulting area under the curve of this chart is significantly greater and/or the half-life of this recombinant interferon in the body is longer than those of the interferon such as interferon alfacon-1 (INFERGEN®), which has the amino acid sequence of SEQ ID NO: 1, but is not encoded by the nucleotide sequence of SEQ ID NO: 2 after injection under the same conditions.

In some embodiments, the present recombinant interferon has the amino acid sequence of SEQ ID NO: 1, and is encoded by the nucleotide sequence of SEQ ID NO: 2, wherein the recombinant interferon has increased inhibitory activities on the expression of hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) of Hepatitis B Virus as compared to an interferon interferon such as interferon alfacon-1 (INFERGEN®), which has the amino acid sequence of SEQ ID NO: 1, but is not encoded by the nucleotide sequence of SEQ ID NO: 2.

In another aspect, the recombinant interferon (rSIFN-co) used in the present invention can be produced by the methods disclosed in, for example, U.S. Pat. No. 7,364,724, U.S. Pat. No. 7,585,647, U.S. Pat. No. 8,114,395, CN 1740197 A, CN 101001644 A, US 2009/0123417, US 2011/0158941 and WO 2011072487A1. In a specific embodiment, the present recombinant interferon can be produced by the method comprising the following steps: introducing a nucleotide sequence comprising SEQ ID NO: 2 that encodes the recombinant interferon into an isolated host cell; culturing the host cell under appropriate condition for expression of the recombinant interferon; and harvesting the recombinant interferon, wherein the recombinant interferon has an amino acid sequence of SEQ ID NO: 1, and the recombinant interferon inhibits secretion of hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) of Hepatitis B Virus. Further, the host cell is Escherichia coli, such as Escherichia coli LGM 194. Further, the nucleotide sequence comprising SEQ ID NO: 2 is under the control of the promoter P_(BAD). Further, the harvesting step comprises extraction of the interferon from the fermentation broth, collection of the inclusion bodies, denaturation and renaturation of the harvested interferon. Still further, the harvesting step also comprises separation and purification of the recombinant interferon.

The person skilled in the art can prepare intramuscular injection dosage form, spray dosage form, or inhalation dosage form and the like of the present recombinant interferon with reference to the contents of the following part D with title of Pharmaceutical composition and administration route.

The specific activity of the present recombinant interferon is in a range of about 4.4×10⁸ IU/mg to about 1.0×10⁹ IU/mg, and optionally greater than 5.5×10⁸ IU/mg. Such specific activity is the ratio of the biological activity and the content of protein. The biological activity is measured by a method well-known by the person skilled in the art such as the biological activity measurement method for the interferon (i.e. the cell lesion inhibition method) published in the Appendix X C in Chinese Pharmacopoeia (the third book), Edition 2010; and the content of the protein is measured by a method well-known by the person skilled in the art such as the second method (i.e. the Lowry method) of protein measurement method published in the Appendix VI B in Chinese Pharmacopoeia (the third book), Edition 2010.

In some embodiments, the tumors are metastasized, and such metastasis can be in situ and in the distance. As used herein and related to cancers or malignant tumors, the term “metastasis” refers to the spread of cancers or malignant tumors from the in-situ position to other in-vivo positions. Cancer cells can separate from in-situ tumors, penetrate into lymphatic vessels and blood vessels, and then grow in distant lesions in normal tissues at other in-vivo positions through blood circulation. The metastasis can be in situ or at the distance. The lung tumors such as lung cancers can metastasize to lymph nodes, brain, central nervous system, bone, liver, adrenal, skin, intestine, thyroid, ovary, prostate and the like. Therefore, the present recombinant interferon can be used for treating these metastasized tumors such as metastasized lung cancers; particularly, the present recombinant interferon can relieve the symptoms caused by partial stress and invasion of the lung cancers to adjacent tissues, and treat the distant metastasis of the lung cancers. The symptoms caused by the partial stress and invasion of the lung cancers include but not limited to dyscatabrosis caused by the metastasis and hyperplasia of lymph node around esophagus as well as dyspnea caused by the spread of tumors through the lung parenchyma lymphatic vessels. The distant metastases of the lung cancers include but not limited to brain metastases of the lung cancers, central nervous system metastases of the lung cancers, bone metastases of the lung cancers, liver metastases of the lung cancers, adrenal metastases of the lung cancers, and other metastases such as skin metastases, thyroid metastases, ovary metastases, prostate metastases and the like of the lung cancers.

E. Administration Dosage and Administration Protocol

Effective amount of the present recombinant interferon can be administered to the subjects such as cancer subjects, and such effective amount can be a therapeutically effective amount or a prophylactically effective amount according to the method of the invention. As used herein, the term “effective amount” refers to an amount effective, at dosages and for periods of time necessary, to achieve the desired therapeutic or prophylactic result. A therapeutically effective amount of the present recombinant interferon may vary according to factors such as the disease state, age, sex, and weight of the individual, and the ability of the recombinant interferon to elicit a desired response in the individual. A therapeutically effective amount is also one in which any toxic or detrimental effects of the recombinant interferon are outweighed by the therapeutically beneficial effects. A “prophylactically effective amount” refers to an amount effective, at dosages and for periods of time necessary, to achieve the desired prophylactic result. Typically but no surely, since a prophylactic dose is used in subjects prior to or at an earlier stage of disease, the prophylactically effective amount will be less than the therapeutically effective amount.

G. Evaluation Standard of Curative Effect and Adverse Effect

The curative effect evaluation on the present recombinant interferon in the aspect of clinical treatment for tumors such as solid tumors adopts the Response Evaluation Criteria in Solid Tumors standard (RECIST standard) published in 1999 (see James, K. et al. J Natl Cancer Inst, 1999, 91, 523-528).

The tumor lesions are divided into measurable lesions and un-measurable lesions, wherein the measurable lesions are defined as target lesions; the longest diameter represents the size of each lesion; at most 5 lesions can be selected in each involved organ, the sum of the measured lesions of all the involved organ is not more than 10, and the sum of the longest diameters of all the lesions is the overall diameter of the target lesion. The un-measurable lesions are defined as non-target lesions, only the existence of the lesions are recorded and tracked, but the sizes of the lesions are not measured.

The curative effect evaluation standard of the target lesion is divided into 4 grades, the curative effect evaluation standard of the non-target lesion is divided into 3 grades, and the overall curative effect evaluation is obtained by combining the curative effects of the two kinds of lesions. It is specifically described as follows:

The curative effect evaluation standard of the target lesions: (1) CR (complete remission): all the target lesions disappear; (2) PR (partial remission): the overall diameter of the target lesions is decreased by more than 30%; (3) NC or SD (no change or stable disease): the target lesions are neither decreased to “PR” nor increased to “PD”; and (4) PD (progression disease): the overall diameter of the target lesions is increased by more than 20%, or one or more new lesions appear.

The curative effect evaluation standard of the non-target lesion: (1) CR: all the non-target lesions disappear, and the tumor marker level is normal; (2) IR (incomplete response)/SD: one or more non-target lesions is/are not changed, and/or the tumor markers exceed the normal limit; and (3) PD: one or more new lesions appear, and/or the non-target lesions are obviously developed.

The overall curative effect evaluation standard of solid tumors.

TABLE 1 The overall curative effect evaluation standard of solid tumors Non-target Overall curative Target lesion lesion New lesion effect CR CR No CR CR IR/SD No PR PR Non-PD No PR NC/SD Non-PD No NC/SD PD Any Yes or No PD Any PD Yes or No PD Any Any Yes PD

The adverse effect evaluation on the present recombinant interferon for clinical treatment for the tumors such as the solid tumors takes the reference to the “WHO” Toxicity Grading Standard.

Compared with the prior art, the recombinant interferon has the beneficial effects as follows:

The recombinant interferon rSIFN-co used in the present invention has obvious different structural features and physiological activities compared with the existing interferons such as INFERGEN® (interferon alfacon-1) of the US Amgen. On one hand, the recombinant interferon can be singly used and/or can be combined with radiotherapy, chemotherapy, biological agents, and/or targeted drugs and the like, so as to non-surgically eliminate or reduce the tumors of the solid tumor subjects, particularly advanced tumors; specifically, the recombinant interferon can eliminate or reduce the solid tumors without indications for surgery, particularly the advanced solid tumors without indications for surgery. On the other hand, the recombinant interferon can be singly administered through topical or local administration such as intratumoral injection/epidermal spray administration and the like, or through the combination of the topical or local administration together with the systemic administration (using the present recombinant interferon or radiotherapy/other anti-tumor drugs and the like), so as to non-surgically (namely, without surgery) eliminate or reduce the solid tumors. Further, the recombinant interferon has obvious effect in replacing the chemotherapy drugs for preventing post-surgery recurrence or metastasis of the tumors, particularly various metastatic lesions such as bone metastasis which cannot be eliminated by existing treatment means; however, drugs can be directly administered to the lesions by the present invention, especially by the topical or local administration, to obviously reduce or eliminate the tumors. In addition, the recombinant interferon can be singly administered through intrapleural or abdominal perfusion so as to for effectively eliminate or decrease malignant pleural effusion and/or malignant ascites.

Furthermore, cancer can be controlled by the rSIFN-co combination therapy. Firstly, the present recombinant interferon (rSIFN-co) has broad-spectrum anti-tumor effects, which is effective on both solid tumors and non-solid tumors while, at the same time, rSIFN-co has a good synergetic effect with existing treatment means such as surgical therapy, chemotherapy, radiotherapy, biotherapy and other anti-tumor drugs. Secondly, rSIFN-co has low toxicity which means no harm to normal cells has been observed when rSIFN-co is used in large doses. Thirdly, rSIFN-co is convenient to use and can be directly applied to tumors in any position. The rSIFN-co can be used by subcutaneous/intramuscular injection to control systemic progress of tumor, by intrapleural/abdominal perfusion to eliminate effusion and intrapleural/abdominal tumors, by topical or local injection to eliminate primary or metastatic tumors, and by infiltration (transdermal) administration to treat tumor lesions in bone, skin, muscle, prostate and the like; and rSIFN-co can also be administered by aerosol inhalation. According to above three advantages of rSIFN-co, effective rate of the combination therapy is no lower than 90%. With regard to early or medium-term cancer cases, rSIFN-co can be used after surgery to replace chemotherapy and effectively prevent recurrence and metastasis; with regard to advanced cancer cases or cancer cases without indications for therapy, rSIFN-co can be used to eliminate tumors without surgery; with regard to cases without indications for surgery, rSIFN-co can be used to transformed the cases into ones with indications for surgery, thereby creating surgical conditions. Therefore, we believe the rSIFN-co combination therapy is capable of curing cancer.

IIIb Regimens before administration of DP Regimen^({circle around (8)}) was provided from October 14, rSIFN-co: Year 1 to November 25, Year 1: 75 mg of Taxotere and 75 mg of Cisplatin on Day 1. Two cycles of chemotherapy were performed in total, each lasting for 21 days. Regimens: administration of rSIFN-co The rSIFN-co therapy started in November, Year combined with radiotherapy 1. Intramuscular injection of rSIFN-co was done once every other day: 9 μg for the 1st time, 15 μg for the 2nd time and 18 μg for the 3rd time and thereafter. Therapy continued till February, Year 3, during which rSIFN-co treatment had been stopped for 1 month in April, Year 2, leading to a total treatment duration of 15 months. Radiotherapy^({circle around (3)}) (DT40Gy) on right lung and mediastinal lymph nodes started on December 2, Year 1 followed by X-knife therapy (DT20Gy) Response to rSIFN-co treatment: CR^({circle around (2)}) (primary lesions on right pulmonary hilum disappeared and cured) Survival time: After about 80 months (from October Year 1~July Year 8), the patient remained alive and lived a normal life. No recurrence or metastasis was observed upon imaging examinations. Diagnostic imaging before administration CT scan on November 25, Year 1 after of rSIFN-co: chemotherapy: The right main bronchus was obstructed by the invasive masses originated from right hilum, resulting in atelectasis of upper lobe of the right lung; multiple nodules occurred at the lower lobe of right lung. These signs indicated progression of tumor. The patient had breathing difficulty and breath sound disappeared. Diagnostic imaging after administration CT scans on January 4, Year 2: of rSIFN-co: The masses at right hilum were reduced in size, relieving atelectasis at the upper lobe of the right lung. Part of mediastinal lymph nodes also decreased in size. CT scans on June 12, Year 2: The mediastinal lymph nodes continued to shrink and infiltration of right lung was absorbed. CT-scan on November 08, Year 2 (12 months after administration): Please refer to the location indicated by arrow in FIG. 3a where the lesions originally occurred. CT-scan on February 1, Year 3 (15 months after administration): Please refer to the location indicated by arrow in FIG. 3a where the lesions originally occurred. CT scan on October 19, Year 3: The blood vessels or lymph nodes on the right hilum were a little larger than normal and more infiltration on lower lobe of right lung was absorbed; other changes were not obvious. Description of FIGS. 3a-3b: After 12 months of treatment, the lesions on the right lung were obviously reduced in size. After 15 months of rSIFN-co administration, progression or metastasis of lesions was not observed.

IV Regimes before administration of rSIFN-co: The first cycle of EP^({circle around (7)}) chemotherapy was conducted from March 25, Year 1 to Apr 9, Year 1: 100 mg of Etoposide and 30 mg of Cisplatin. Regimes: administration of rSIFN-co The treatment of rSIFN-co began on April 12, combined with chemotherapy and Year 1. Intramuscular injection was done interventional therapy once every other day: 9 μg for the 1st time, 15 μg for the 2nd time and 18 μg for the 3rd time and thereafter. Aerosol inhalation of rSIFN-co was performed once every other day: 0.5~2 ml/dose (200 μg/ml). From July 16, Year 1, 21 μg of rSIFN-co was used in intramuscular injection. Aerosol inhalation of rSIFN-co continued but the amount per dose was changed to 200 μg. The first cycle finished by the end of March Year 2 (lasting for almost 1 year). The administration of rSIFN-co was stopped for 1 month because Aerosol inhalation of Cisplatin (one dose per day and 10 mg per dose) was performed throughout September Year 1. The 2nd cycle of treatment proceeded from October 9, Year 2 to January 26, Year 3 during which 18 μg of rSIFN-co was intramuscularly injected every other day. Five cycles of EP chemotherapy were conducted from March 25, Year 1 to September 10, Year 1 and the same regimen as mentioned above was used. An interventional cryoablation was conducted on the supraclavicular lesions on September 3, Year 2. From October Year 1, a 15-day regimen of aerosol inhalation of Cisplatin was added: 10 mg per dose, 1 dose per day. Two cycles were done, each lasting for 15 days. Response to rSIFN-co treatment: CR^({circle around (2)})(a primary lesion of about 0.6 × 0.4 cm, on the apex of right lung disappeared.; a lesion with a nodule of about 2.6 × 2.2 cm on the of right clavicle disappeared; Mutilple nodules appearing in neighboring areas of the mediastinal brachiocephalic trunk, right brachiocephalic veins, superior vena cava, and trachea, part of which fused and lesions of about 5.5 cm × 4.9 cm in size disappeared.) Survival: After about 39 months (from March 23, Year 1 to July Year 4), the patient remained alive and had a normal life. No recurrence or metastasis was observed upon imaging. Diagnostic imaging before administration of Diagnostic imaging after administration of rSIFN-co: rSIFN-co: PET/CT scans on April 8, Year 1 (see the PET/CT scans on December 24, Year 1 (see lesions indicated by arrows in FIG. 7a-8a) the original lesion locations indicated by after the chemotherapy: arrows in FIG. 7a-8a): 1.

After cryotherapy was conducted for the right supraclavicular metastasis, no obvious nodules or masses were found in the right clavicle and PET image did not show obvious radioactive concentration. PET scans on other parts showed similar metabolic images as before. PET/CT on February 7, Year 4 (after treatment of “small-cell cancer of right lung” and compared to PET/CT scans taken on July 26, Year 3): 1. The posterior wall of left nasopharynx was thickened slightly and PET imaging showed radioactive concentration, suggesting the possible occurrence of an inflammatory lesion; 2. Multiple nodules were at deep cervical and submentum and PET imaging did not show abnormal radioactive concentration, suggesting the possible occurrence of inflammatory hyperplasia of lymph nodes; 3. The wall of greater gastric curvature was slightly thickened and PET imaging did not show radioactive concentration. Inflammatory lesion could be taken into consideration; 4. PET/CT scans on other parts did not show significant changes. Description of FIGS. 7a-7b: After 8 months of treatment, the lesions on the apex of the right lung disappeared. Description of FIGS. 8a-8b: After 8 months of treatment, the metastatic lesions in mediastinum disappeared.

After treatment, the metastatic lesions in right lung hilum, paratracheal lymph nodes and several sites of spinal metastases disappeared.

Patient 5 Gender: Female Age: 42 Pathological diagnosis^({circle around (1)}): Metastatic adenocarcinoma (in right humerus) (moderately differentiated adenocarcinoma) Clinical and pathological staging^({circle around (1)}): T₂N₂M_(1.) IV Regimes before administration of rSIFN-co: A surgical repair of right humerus was performed on February 23, Year 1. After that surgery, patient was given 4 courses of DP^({circle around (8)}) chemotherapy: 75 mg of Taxotere and 75 mg of Cisplatin on day 1. Regimes: administration of rSIFN-co Treatment with rSIFN-co began on April 15, combined with chemotherapy Year 1. Intramuscular injection was performed once every other day: 9 μg for the 1st time and 21 μg for the 2nd time and thereafter. The treatment was provided for a total of 3 months till September 15, Year 1, during which rSIFN-co administration was suspended for 1 month due to chemotherapy (the chemotherapy regimen shown below related to aerosol inhalation of Cisplatin) and for 1 month because of the patient's physical condition. Aerosol inhalation of rSIFN-co was added on September 16, Year 1: 1 ml (200 μg/ml) per day. Till February, Year 2, the co-administration regimen was provided for 5 months. From September 15, Year 2, intramuscular injection of 15 μg was provided every other day. Aerosol inhalation of Cisplatin began on September 16, Year 1: 10 mg per dose and 2 doses per day. Eight cycles were conducted with each cycle being 15 days. Response to rSIFN-co treatment: CR^({circle around (2)})(radioactive concentrations at the primary lesion of right lung tumor, right humerus and the T6 vertebra evidently decreased.
